"[4] Nick Harley of Den of Geek gave the episode a 4 star rating out of 5 and wrote, "If the Righteous Gemstones has more aces up its sleeve like Baby Billy, then we could really be in for something special here.
With the flashes of genuine heart and the extensive world-building, Gemstones is adding delicious layers to its twisty Fargo-esque crime story.
"[5] Kevin Lever of Telltale TV gave the episode a 4 star rating out of 5 and wrote, "Something 'They Are Weak, But He Is Strong' manages to convey is that despite disappointment, despite the scheming, there is a closeness behind all of the snide remarks.
